Light manipulation with plasmonic nanoantennas

We focus on the optical response of metallic nanowires and nanowire composites. Because nanowires and their composites can act as antennas, we can use the terms "nanoantenna" and "nanowire" interchangeably. We explore the electromagnetic properties of nanostructured plasmonic antennas and show that they can be effectively used for light nano-confinement, field enhancement, and allow one to achieve left-handed response from the nanoantenna composite.
